Oceanographer Creates Algorithm to Remove Water From Underwater Images

Coral reefs are among nature’s most complex and colourful living formations. But as any underwater photographer knows, pictures of them taken without artificial lights often come out bland and blue. Even shallow water selectively absorbs and scatters light at different wavelengths, making certain features hard to see and washing out colours—especially reds and yellows. This effect makes it difficult for coral scientists to use computer vision and machine-learning algorithms to identify, count and classify species in underwater images; they have to rely on time-consuming human evaluation instead. But a new algorithm called Sea-thru, developed by engineer and oceanographer Derya Akkaynak, removes the visual distortion caused by water from an image. The effects could be far-reaching for biologists who need to …

Oh Good, Boston Dynamics Has Robots Doing Parkour Now

In this incredible demonstration by Boston Dynamics’ robot, Atlas, we see the machine executing a series of gymnastic/parkour maneuvers. Boston Dynamics adds: Atlas uses its whole body — legs, arms, torso — to perform a sequence of dynamic maneuvers that form a gymnastic routine. We created the maneuvers using new techniques that streamline the development process. First, an optimization algorithm transforms high-level descriptions of each maneuver into dynamically-feasible reference motions.   Then Atlas tracks the motions using a model predictive controller that smoothly blends from one maneuver to the next. Using this approach, we developed the routine significantly faster than previous Atlas routines, with a performance success rate of about 80%. Original Article : HERE ; The Ultimate Survival Food: …

This is How Fast a CT Machine Spins at Max Speed

I only know three things about CT machines: They’re loud, they’re expensive, and the images they produce can be useful to people far smarter than me. And after watching this, I now know they spin incredibly fast (considering how heavy the components inside appear to be). According to the YouTube description this is a Canon Aquilion going at full speed with its cover off. A technician was doing some small repairs on this CT and the hospital staff asked if they could take it for a spin while it’s cover plate was removed.Clearly balancing the weight distribution inside the machine is quite important!
